Hidden Costs Of Cheap HVAC Filters

There are many hidden costs that come with using cheap HVAC filters, even if they seem like a good deal at first. These filters may lead to problems over time. Keep reading to learn more about the hidden costs you might face from choosing to use cheap HVAC filters.

1. Dirty Indoor Air Quality

Poor indoor air quality results from cheap HVAC filters, which often fail to capture small pollutants like dust, allergens, and volatile organic compounds (VOCs). These pollutants can cause allergies, respiratory disorders, and other kinds of serious health problems if they remain in the air. Low-quality air filters could ignore tiny, dangerous particles, letting them move freely throughout your house. This can eventually cause the indoor air quality to feel unhealthy and unclean. A lot of individuals choose better filters or install air purification systems in their homes to improve the quality of the air they breathe and lower pollutants.

2. Rising Energy Bills

Your HVAC unit may use more energy if you use cheap air filters. Your HVAC system will have to work harder to heat or cool your house if these HVAC filters quickly clog up and block the airflow. Your monthly energy consumption increases when the HVAC system works longer than necessary. In addition, this increased work pressure may cause HVAC parts to break down more quickly and result in more HVAC repair calls. Cheap filters might start out less expensive, but they may slowly raise your expenses over time. An improved filter reduces energy efficiency and makes the system function more smoothly, leading to long-term cost savings.

3. Constant Filter Replacements

Cheap HVAC filters, especially fiberglass ones, often build up dust and debris very quickly. They must be changed more frequently to maintain the HVAC system's smooth functioning because they clog more rapidly. These air filters typically do not hold a lot of debris, so they immediately stop functioning correctly. It can be exhausting to change air filters every few weeks, and the costs eventually increase. At first view, they might seem like a good deal, but over time, the need for more frequent replacements may make them more costly than higher-quality alternatives, especially when paired with repeated HVAC service calls.

4. Risk Of HVAC Damage

Cheap HVAC filters cannot properly guard your system, allowing dust and debris to get through and collect on parts like the motor and coils. The HVAC unit may have to work harder as a result, which could cause damage and overheating. Clogged components have the potential to slow down or even stop the system from functioning over time. It can be costly to replace or repair damaged HVAC parts. The cost may be even greater if the system fails entirely, leading to major HVAC repair or even new HVAC installation. Although using poor air filters can help you save money in the beginning, it can later cause expensive issues.

Frequently Asked Questions

What Does The MERV Rating On HVAC Filters Mean, And Why Is It Important?

The MERV rating on HVAC filters shows how well a filter can catch tiny particles in the air. A higher MERV number means the filter can trap smaller things like pollen, dust, smoke, and even some germs. This helps keep the air inside your home cleaner. Picking the right MERV filter matters because it can protect people with allergies or breathing problems. It also helps your HVAC system run better by keeping dust and dirt out. But if the MERV number is too high for your system, it can block airflow. So, it is best to choose a filter that matches your system's needs.

Can Using The Wrong Size Filter Damage My HVAC System?

Yes, using the wrong size air filter can cause problems for your HVAC system. If the filter does not fit right, air may not move through it properly. This can make the system work harder than it should, which can lead to parts wearing out faster. A filter that is too small might also let dirt and dust get inside the system. This can lead to clogs or even damage to parts like the motor or coils. To keep things running smoothly, always check the size before buying a new filter. Look at your HVAC system’s manual or ask a professional if you are not sure what size is right. This helps your system last longer and run better.

How Do HVAC Filters Affect Noise Levels From The System?

HVAC filters can have a big effect on how much noise your system makes. When a filter gets full of dust and dirt, it blocks the air from moving through easily. This makes the blower motor work harder, and that can cause louder sounds from the system. Over time, this can also wear out parts faster. A clean filter helps the air move smoothly and keeps the system running quieter. If the filter is the wrong size, it can also make the system louder. Checking your filter often and replacing it when needed is a simple way to keep noise levels down and help your HVAC system work better for longer.

Can HVAC Filters Help Reduce Pet Dander And Odors In The Home?

Yes, HVAC filters can help cut down pet dander and bad smells in your home. Pets shed skin flakes and fur that float in the air, and a good filter can trap these small bits before they spread. Some filters, like ones with carbon, can also take in smells, so your home feels fresher. If you or someone in your home has allergies, using the right filter can make breathing easier. Look for filters made to catch smaller things in the air. Changing the filter on time is just as important, as a dirty one will not work well. If you have more than one pet, you might need to check your filter more often than usual.

Are Washable HVAC Filters A Good Alternative To Disposable Ones?

Washable HVAC filters can be a smart choice if you want to save money over time and cut down on waste. They last for years and do not need to be replaced as often as disposable ones. Some people also say they catch more dust than the cheaper fiberglass filters. But they do not trap tiny particles as well, so they may not be the best if you have allergies or pets. You also need to wash them often and make sure they dry fully, or they might grow mold. If you are okay with cleaning and want something that lasts, washable filters can be a good pick for your HVAC system.

Can HVAC Filters Filter Out Viruses Or Bacteria Effectively?

HVAC filters can help reduce viruses and bacteria in the air, but not all filters are equally effective. Standard filters with low MERV ratings mostly trap dust and large particles. To filter out smaller things like viruses and bacteria, you need a high-efficiency filter, such as a HEPA filter or a filter with an MERV rating of 13 or higher. These filters can capture tiny airborne germs, but they still might not remove everything. Using UV lights or air purifiers along with good filters can help improve results. Also, filters need to be changed or cleaned often to keep working well. So while filters help, they should be part of a full air cleaning plan.

What Types Of HVAC Filters Are Available Besides Cheap And High-Quality Options?

Besides the cheap and high-end HVAC filters, there are a few other types that suit different needs. Pleated filters are a good middle option and do a decent job of catching dust and dirt. HEPA filters are stronger and can trap really small particles, which is helpful for people with allergies. Electrostatic filters use a charge to pull in dust and can be washed or replaced. Activated carbon filters help with smells and can catch some gases, too. When picking a filter, it is smart to check the MERV rating, which tells how well it can trap stuff. Also, think about how often you want to clean or replace it, as some need more care than others.
